WebPd x Ni y /TiO 2 bimetallic electrocatalysts were used in fuel cell polymeric electrolyte reactors (PER-FC) to convert methane into methanol through the partial oxidation of methane promoted by the activation of water at room temperature. X-ray diffraction measurements showed the presence of Pd and Ni phases and TiO 2 anatase phase. … Web7.2.2 Methane Reagent Gas Plasma The EI mass spectrum of methane has already been discussed (Chap. 6.1). Rising the partial pressure of methane from the standard value in EI of about 10–4 Pa to 102 Pa significantly alters the resulting mass spectrum. [1] The molecular ion, CH4
